The Stack Matrix · Business OS
Turn a business question into a plan you can revisit.
Compare your assumptions, record what happened, and choose your next move. Finance, Pricing, Sales, and Marketing tools meet a protected workspace for saved plans, monthly results, and business reviews.
Plan → measure → decide
A repeatable loop for real business questions.
Keep your assumptions, customer-entered results, and decisions connected through tools and saved-work links. You choose what to record and when to save. The workspace does not run your business for you.
01 / Plan
Start with a question, not a blank workspace.
Use Start here to choose cash flow, pricing, sales pipeline, or marketing. Compare editable assumptions in an existing kit and explicitly save the option you want to revisit.
Illustrative question, not a customer result
What happens to cash if receipts arrive later?
A saved scenario with assumptions you can restore.
02 / Measure
See what you reported beside what you planned.
Record monthly results with optional targets and forecasts. Explore the overview's trend charts without filling missing values or confusing profit with cash.
Illustrative question, not a customer result
How did this month's reported result compare with my target?
A month-specific view; blank is unreported, not zero.
03 / Decide
Keep the reasoning. Give the next step a date.
Write a weekly or monthly review, record decisions, and date your follow-ups. Overview surfaces due saved-work reminders so you can return to the question.
Illustrative question, not a customer result
What should I keep, change, or test next?
A decision or review you can revisit, not automated advice.
One connected workspace
The four kits, plus a place to keep reviewing.
Business OS includes access to the Finance, Pricing & Unit Economics, Sales & Revenue, and Marketing & Customer Growth kits while your verified subscription provides access.

Know what you are choosing.
Who is Business OS for?
Business owners, freelancers, and small-business operators who want to explore assumptions and maintain a planning-and-review habit. Saved work is private to your account, not a shared team workspace. Start with one question; you do not need to fill every tool or metric.
Does it replace accounting software or a CRM?
No. This is a business-planning workspace, not an accounting ledger, CRM, payroll system, or ERP. Results are entered by you; there is no automatic bank, bookkeeping, or CRM sync.
Are the forecasts or results verified?
Forecasts are estimates based on your assumptions, not guaranteed outcomes. Observed results are customer-entered, not independently verified. Missing values remain unreported. Review context reflects currently loaded records, not a frozen historical snapshot.
Does it publish marketing content or send reminders?
The customer-facing Marketing Kit supports planning, measurement, editable content drafts, and human review. It does not automatically publish content. Business OS reminders appear in the workspace; they do not schedule email notifications. Owner-only internal marketing integrations are not included.
How do I start after subscribing?
Sign in with the account used for checkout. Access requires verified subscription confirmation; returning from checkout alone does not activate it. Open Start here, choose a question, replace tool defaults with your own assumptions, and save explicitly.
